A quadrilateral with two pairs of parallel sides is called?

• A. Parallelogram
• B. Trapezoid
• C. Rhombus
• D. Quadrilateral

Answer: (A)

Two pairs of opposite sides that are parallel define a parallelogram. In this shape, both pairs of opposite sides run in the same directions, so the figure closes smoothly and opposite sides are equal as a consequence. A trapezoid has only one pair of parallel sides, so it doesn’t fit this property. A rhombus is a special kind of parallelogram where all sides are equal, but it still has two pairs of parallel sides, and the general name for the shape with that property is parallelogram. A quadrilateral is any four-sided figure and doesn’t specify parallel sides.
